以玻璃微电极细胞内记录技术，研究了正常和模拟缺血再灌注条件下，豚鼠右心室游离壁的内、外膜下传导和跨壁传导等心肌传导特性。结果显示，在心肌缺血和再灌注过程中，兴奋在豚鼠右心室内膜下的扩布有所减慢但无方向性差异，心外膜不同方向上的传导差异则显著增大。同时，。Ｃ室肌外向和内向跨壁传导时间均有明显性延长，部分标本甚至出现完全性跨壁传导阻滞。，Ｇ肌传导特性的这种不均一性变化，为缺血和再灌注过程中折返激动的发生提供了有利条件。
Using glass microelectrode intracellular recording technique, the intramyocardial and epicardial conduction and transmural conduction and other myocardial conduction characteristics of guinea pig right ventricular free wall under normal and simulated ischemia-reperfusion were studied. The results showed that in the process of myocardial ischemia and reperfusion, the excitement in the right ventricular endocardium in guinea pigs had a slow but no directional difference, and the differences in conduction in the epicardium were significantly increased. Simultaneously,. C room muscle and inward transmembrane conduction time were significantly longer, some even complete transmural block. This inhomogeneous change in G-muscle conduction properties provides favorable conditions for the occurrence of reentry activation during ischemia and reperfusion.
